Final answer:
The Addams Family Musical had its trial run in Chicago, 2008, before moving to Broadway the following year. Option A
Step-by-step explanation:
The trial run for The Addams Family Musical took place in Chicago during the year 2008. Like the follow-ups to other prominent theatre productions, the show had its pre-Broadway engagement outside of New York to gauge the reaction from audiences and critics.
For example, Kinky Boots first opened in Chicago before it made its way to Broadway, and Moulin Rouge debuted in Boston prior to moving to New York.
This common practice allows producers to finetune the show based on the feedback received during these trial runs. In the case of The Addams Family, the musical then moved to Broadway in 2010 after the Chicago premiere. Option A
